Abstract

Purpose

The literature on job crafting has paid scant attention to the role of skill variety, one dimension of job characteristics, as a predictor of employee job crafting. By integrating regulatory focus and social exchange perspectives with job crafting literature, the authors investigate how skill variety promotes employee job crafting and the moderating roles of employee's promotion focus and procedural justice climate.

Design/methodology/approach

The authors conducted two questionnaire surveys, one with a sample of 205 employees from a variety of organizations in China, and the other one with a sample of 265 employees within 44 work groups at a state-owned enterprise in China, to examine the hypotheses.

Findings

Results suggest that a high level of skill variety within a job promotes employee job crafting, that such an effect is stronger when the employee's promotion focus is high rather than low, and that procedural justice climate mitigates the negative influence of a low level of promotion focus.

Originality/value

The authors' findings suggest that both self-regulatory and social exchange mechanisms play a critical role in promoting employee job crafting when individuals are engaged in jobs that entail a high level of skill variety.

Abstract

Purpose

Social networking sites (SNSs) are an indispensable part of people’s daily lives. However, scant literature describes how SNSs affect users’ behaviors, especially consumer behavior in emerging markets. This research aims to fill this literature gap.

Design/methodology/approach

Two empirical studies were conducted using different methods. Study 1, a survey, provided correlational evidence. Study 2, a lab experiment, further verified the causal relationship.

Findings

From Chinese consumer data, SNS consumption exposure enhances luxury brand consumption, mediated by social comparison motivation and moderated by legitimacy perceptions of SNSs as information outlets.

Originality/value

This research bridges SNSs and luxury brand consumption, two islands among different streams of literature. In addition, the paper illuminates the psychological mechanism through which SNSs affect luxury brand consumption and the boundary condition in which this effect diminishes. Practically, this paper is also instructive for SNSs and luxury brands.

Abstract

Purpose

This paper examined the relationship between firm innovativeness and consumer trust in the sharing economy. In addition, the authors examine the mediating effect of organizational legitimacy and the moderating effect of social worth.

Design/methodology/approach

To examine the hypotheses, the authors collected data from 276 users of a sharing platform (Didi) in China to conduct empirical research. The “lavaan” packages in R and SPSS were used to analyze the data and test the proposed hypotheses.

Findings

The results reveal that sharing platforms' innovativeness is positively related to consumer trust, and this relationship is mediated by organizational legitimacy. Furthermore, sharing platforms' social worth moderates the relationship between firm innovativeness and organizational legitimacy as well as the indirect effect of firm innovativeness on consumer trust via organizational legitimacy.

Practical implications

This article proposes strategies that enable sharing platforms to increase consumer trust, which can also better promote the development of the sharing economy.

Originality/value

This paper contributes to the literature by focusing on the social attributes of the sharing economy. By building a more detailed model of consumer trust, this paper adds to the knowledge on the influencing mechanism of consumer trust in the sharing economy.

Abstract

Purpose

The purpose of this paper is to find how leader humility affects employees’ constructive voice behavior toward supervisor (speaking up) and coworkers (speaking out) from an identification-based perspective, and seeks to verify the effectiveness of leader humility in the Chinese context.

Design/methodology/approach

Data were collected from 325 employees in four Chinese companies with two phases. In the first phase, the participants were asked to report the leader humility, their identification of their relations with the supervisor, and their identification with their organization. In the second phase, they were asked to report their voice behaviors toward their supervisors and coworkers.

Findings

The results indicate that leader humility strongly predicts both employees’ voice behaviors of speaking up and speaking out. Results further suggest that relational identification with the supervisor explains why leader humility promotes employees speaking up, while organizational identification explains why leader humility promotes employees speaking up and speaking out.

Practical implications

Managers with humility can successfully shape employees’ relational and organizational identifications, which in turn encourage their voice behaviors toward supervisors and coworkers. Hence, behaving humbly in working places could be an effective way for managers to promote organizational cohesion and creativity.

Originality/value

Although leader humility attracts much attention in both academia and practice, researchers have been primarily focusing on conceptual development and measurement issues, and empirical studies are rare. This is the first research connecting leader humility and employee proactive behaviors. Moreover, it takes an in-depth analysis of the constructive voice behaviors by differentiating them based on their targets.

Abstract

Purpose

The purpose of this paper is to investigate the effect of conspicuous consumption on brand attitudes in the context of luxury brands market in China.

Design/methodology/approach

Two studies are conducted to test three hypotheses. In Study 1, the authors examine the mediating effect of self-brand association (SBA) on the relationship between social class and conspicuous consumption (H1 and H2); In Study 2, the authors examine the effect of observing others’ conspicuous consumption on the observer’s SBA (H3).

Findings

Results show that SBA negatively mediates the relationship between social class and conspicuous consumption. Moreover, the negative effect on SBA of observing conspicuous brand usage varies by social class.

Research limitations/implications

The current study focused on the principal linkage between social class, SBA and conspicuousness, and future research could examine the influence of different personality traits on luxury consumption or the existence of sub-types or variants of conspicuous brand users.

Originality/value

The present study has important implications for luxury brand management, and provides rich insights to consumers’ motivations that lead to distinctive luxury consumption behaviors.

Abstract

Purpose

In spite of the vehicle, magnetic field interference can be reduced by some measures and techniques in ammunition design and manufacturing stage, the corruption of the vehicle magnetic field can still reach hundreds to thousands of nanoteslas. Besides, the magnetic field that the ferromagnetic materials generate in response to the strong magnetic field in the vicinity of the body. So, a real-time and accurate vehicle magnetic field calibration method is needed to improve the real-time measurement accuracy of the geomagnetic field for spinning projectiles.

Design/methodology/approach

Unlike the past two-step calibration method, the algorithm uses a linear model to calibrate the magnetic measurement error in real-time. In the method, the elliptical model of magnetometer measurement is established to convert the coefficients of hard and soft iron errors into the parameters of the elliptic equation. Then, the parameters are estimated by recursive least square estimator in real-time. Finally, the initial conditions for the estimator are established using prior knowledge method or static calibration method.

Findings

Studies show the proposed algorithm has remarkable estimation accuracy and robustness and it realizes calibration the magnetic measurement error in real-time. A turntable experiments indicate that the post-calibration residuals approximate the measurement noise of the magnetometer and the roll accuracy is better than 1°. The algorithm is restricted to biaxial magnetometers’ calibration in real-time as expressed in this paper. It, however, should be possible to broaden this method’s applicability to triaxial magnetometers' calibration in real-time.

Originality/value

Unlike the past two-step calibration method, the algorithm uses a linear model to calibrate the magnetic measurement error in real-time and the calculation is small. Besides, it does not take up storage space. The proposed algorithm has remarkable estimation accuracy and robustness and it realizes calibration the magnetic measurement error in real time. The algorithm is restricted to biaxial magnetometers’ calibration in real-time as expressed in this paper. It, however, should be possible to broaden this method’s applicability to triaxial magnetometers’ calibration in real-time.

Abstract

Purpose

This study presented the experience of improving the nucleic acid sample collection and transportation service in response to the epidemic. The main purpose is that through intelligent path planning, combined with the time scheduling of sample points, the process of obtaining results to determine the state of COVID-19 patients could be speeding up.

Design/methodology/approach

The research optimized the process, including finding an optimal path to traverse all sample points in the hospital area via intelligent path planning method and standardizing the operation through the time sequence scheduling of each round of support staff to collect and send samples in the hospital area, so as to ensure the shortest time in each round. And the study examines these real-time experiments through retrospective examination.

Findings

The real-time experiments' data showed that the proposed path planning and scheduling model could provide a reliable reference for improving the efficiency of hospital logistics. Testing is a very important part of diagnosis and prompt results are essential. It shows the possibility of applying the shortest-path algorithms to optimize sample collection processes in the hospital and presents the case study that gives the expected outcomes of such a process.

Originality/value

The value of the study lies in the abstraction of a very practical and urgent problem into a TSP. Combining the ant colony algorithm with the genetic algorithm (ACAGA), the performance of path planning is improved. Under the intervention and guidance, the efficiency of hospital regional logistics planning was greatly improved, which may be of greater benefit to critical patients who must go through fever clinic during the epidemic. By detailing how to more rapidly obtain results through engineering method, the paper contributes ideas and plans for practitioners to use. The experience and lessons learned from Tongji Hospital are expected to provide guidance for supporting service measures in national public health infrastructure management and valuable reference for the development of hospitals in other countries or regions.

Purpose

The purpose of the paper is to separate and purify flavonoids existed in Lamiophlomis rotata (Benth.) Kudo. by macroporous adsorption resin (MAR) mixed-bed technology.

Design/methodology/approach

The adsorption and desorption parameters were characterized by UV-VIS spectrophotometry. The optimal MAR mixed bed was screened based on the adsorption experiments; the experiment process was investigated by the order of single, two and three MAR mixed bed separately; and the adsorption performance, which was composed by the authority of 80 per cent adsorption ratios and 20 per cent desorption ratios, was adopted to screen MAR mixed bed for flavonoids. The adsorption dynamic investigated the order of reaction first, and then the adsorption mechanism was researched further. The adsorption thermodynamic investigated the adsorption isotherm first, and then the adsorption feature was analyzed.

Findings

This research found that MAR mixed bed of LS-840 + LSD301 with mass ratio of mLS840:mLSD301 = 3:2 was the optimized combination, and the optimal conditions of the adsorption were volume V = 50 mL, time t = 6.5 h, T = 40°C. The desorption conditions were ethanol content = 70 per cent, desorption time t = 3.0 h, T = 40°C. The adsorption dynamic experimental data fitted better to the pseudo-second-order, and the intra-particle-diffusion model was more suitable for expression of the adsorption mechanism in mesopores process, whereas the homogeneous particle-diffusion model was more suitable in microspores. The adsorption was a physical and multilayer adsorption, and the adsorption driving force was disappeared as it transferred to the fourth layer.

Practical implications

Find an efficient way to separate flavonoids that useful for human’s health, which can not only utilize of plant resources effectively, but also make outstanding contributions to medical industry. It has very high economic and social value.

Originality/value

This contribution provided a new way to separate flavonoids from Lamiophlomis rotata (Benth.) Kudo. Under the optimal conditions, the adsorption rate (F) of MAR mixed bed LS-840 + LSD301 to the flavonoids was 97.81 per cent, the desorption rate (D) was 90.02 per cent and the purity of flavonoids was dramatically increased about 2.08 fold of the crude extract from 28 to 58.4 per cent, and the recovery yield of flavonoids arrived at 91.6 per cent after a circle of adsorption/desorption operation.

Abstract

Purpose

The authors provide firm-level evidence that external financing affects international trade in a way different from internal financing.

Design/methodology/approach

The authors separate new entrants from incumbent exporters and investigate the roles of external and internal financing in export market participation and export quantity.

Findings

The authors find that external financing is of particular importance, as well as internal financing, in helping a firm become a new exporter. By contrast, external financing, unlike internal financing, is not significantly important for an incumbent exporter to stay in the international market. Regarding export quantity, a firm's internal financing is positively associated with more export quantity, whereas external financing is not.

Originality/value

The authors’ findings are consistent with the existence of significant fixed cost for entering the export market and external financing is particularly needed to cover such cost. Meanwhile, the financial need for maintaining the export status is much less and can be satisfied via internal financing.

Abstract

Purpose

This work aims to evaluate the influence of rheological properties of building materials on the bonding quality and ultimate tensile strength in the fused deposition modeling (FDM) process, through the investigation of parts printed by semi-crystalline and amorphous resins. Little information is currently available about the influence of the crystalline nature on FDM-printed part quality.

Design/methodology/approach

Semi-crystalline polyamide 12 and amorphous acrylonitrile butadiene styrene (ABS) were used to assess the influence of rheological properties on bonding quality and the tensile strength, by varying three important process parameters: materials, liquefier temperature and raster orientation. A fractography of both tensile and freeze-fractured samples was also investigated.

Findings

The rheological properties, mainly the melt viscosity, were found to have a significant influence on the bonding quality of fused filaments. Better bonding quality and higher tensile strength of FDM parts printed with semi-crystalline PA12, as compared with amorphous ABS, are suggested to be a result of higher initial sintering rates owing to the lower melt viscosity of PA12 at low shear rates. Near-full dense PA12 parts were obtained by FDM.

Originality/value

This project provides a variety of data and insight regarding the effect of materials properties on the mechanical performance of FDM-printed parts. The results showed that FDM technique allows the production of PA12 parts with adequate mechanical performance, overcoming the greatest limitation of a dependence on amorphous thermoplastics as a feedstock for the production of prototypes.
